Izinto ezizibanayo ezisetshenziswa kuhho lokushisela udoti oyingozi zibalwa ngezingxenye eziyinkimbinkimbi nezingazinzile.Inhloso yokubala iwukushisa imfucuza eyingozi ibe yi-slag kanye nokunciphisa izinga lokunciphisa ukushisa kwensalela libe ngaphansi kuka-5%.lapho kungekho uqweqwe kuhho , indlela yokukhetha ephikisayo yesiko lokushisela imfucuza eyingozi iwuhlobo oluhluke ngokuphelele kuhhavini elijikelezayo.
Okwezinto eziphikisayo ezisetshenziswa kuhhavini elijikelezayo ekwelapheni imfucuza eyingozi, ukwakheka kwamakhemikhali emfucumfucu eyingozi kuyinkimbinkimbi ngenxa yezinhlobo zayo ezihlukahlukene, ngakho-ke kunqunywa ukuthi ukwakheka kwamakhemikhali emfucumfucu eyingozi kushiswe ekushiseni okungama-700-1000 kuma-rotary kilns, futhi ukwakheka okuyinhloko kokukhishwa kwegesi ngemva kokubalwa kukadoti oyingozi kune-asidi encane.
Ku-refractory, i-refractory castable kugesi ene-acidic inozinzo oluhle, i-AL2O3 SiO2 i-waste rotary kiln iwukumelana nokugqwala okuhle kanye ne-castable refractory, lapho ukhetha izinto eziphikisayo, hhayi ukukhethwa kwemikhiqizo ephikisayo, okuqukethwe kwe-Fe2O3 ngangokunokwenzeka ngenxa ye-Fe2O3 FeCL3 isabela nayo. igesi ye-chlorine, isigaba segesi, isitini esishintshashintshayo, esishintshashintshayo futhi esiqina ngokweqile, ihhavini likasimende elijikelezayo livame ukusetshenziswa ekuphikisweni kokugqwala komkhiqizo wokuvikela imvelo iMagnesia iron spinel brick, kudoti oyingozi ukukhethwa kwezinto eziphikisayo eziphikisayo akufanelekile, endaweni eyingozi. imfucuza rotary kuhnu feed kanye outlet castable, kufanele futhi kukhethwe ongaphakeme usimende castable, ngoba usimende CaO kanye ukusabela chlorine, ukwakheka liquid isigaba CaC1 kuzonciphisa ukumelana ukushisa kanye izinga lokushisa eliphezulu ukuzinza of castable.
Ekukhetheni izinto eziphikisayo, ihhavini elijikelezayo lemfucuza eyingozi kufanele lisebenzise izinto eziphikisayo ezinokumelana nokugqokwa okuhle, ukuzinza kokushaqeka okushisayo kanye nokumelana nokugqwala. Inqubo yokukhiqiza ihhoni le-rotary yemfucuza eyingozi ngokuvamile isebenzisa inqubo yokushiswa komfula. Imfucumfucu eyingozi yomoya eyinhloko ingena isuka ohlangothini olulodwa kanti ubude behhashi bufushane (isilinganiso sobude bobubanzi ngokuvamile singu-3-5m kuphela). Ukusabela kuhhavini kulula, okungukuthi, ukusabela kwe-oxidation evuthayo. Phakathi kwemikhiqizo yamanje evamile, isitini se-mullite sic siwumkhiqizo ofaneleka kakhudlwana, futhi izinto ezigaywayo zingakhethwa i-mullite.
